Portable DC Low Resistance Tester

Ultra-high resolution down to 0.001mΩ (1μΩ) on 6310B – detects extremely small resistance changes in contact resistance, bond testing, and shunt measurements.

Model 6310B measurement range (0.001mΩ ~ 300.0kΩ) – covers nine ranges from ultra-low milliohms to hundreds of kilo-ohms for maximum application flexibility.

Model 6310A measurement range (0.01mΩ ~ 30.00kΩ) – seven ranges optimized for most industrial low-resistance testing needs.

High test current up to 1.2A – ensures stable, repeatable readings on inductive loads like transformer windings and motor coils.

Accuracy ±0.1%FS ±20dgt (18~28°C, <70%RH) – delivers reliable, repeatable results for quality control and certification.

Four-wire (Kelvin) detection method – eliminates test lead resistance error for true low-resistance measurements.

500-set internal data storage – saves measurements on-device for later review without external software.

USB data upload function (6310B only) – transfers stored data to a PC for reporting, analysis, and record keeping.

Rechargeable battery (DC 3.7V 2000mAh) – built-in lithium battery eliminates frequent alkaline battery replacements.

Overload protection – safeguards the instrument from accidental connection to live circuits or excessive current.

Overvoltage protection and overflow display – prevents damage from voltage spikes and clearly indicates out-of-range conditions.

Low voltage prompt – warns when battery charge is low to ensure measurement reliability.

Large LCD display with adjustable backlight (72×55mm) – clear readings in dim environments; backlight controllable for power saving.

Automatic shut-down – preserves battery life when the tester is accidentally left on.

Data retrieval function – recall stored measurement sets directly on the instrument without a PC.

Wide application coverage – measures cable wire resistance, switch/connector/relay contact resistance, coil/motor/transformer winding resistance, metal riveting and bonding resistance, grounding grid resistance, and connection resistance between metal components.

Open circuit voltage ≤4.2V – safe for testing sensitive components without damage.

Measuring power ≤8W – energy-efficient operation for extended battery life.

Compact instrument size (187×119×50mm) – portable for field use yet stable on a lab bench.

Excellent multi-auxiliary function design – combines USB, auto shut-down, overflow display, low voltage prompt, large screen, overvoltage protection, data retrieval, and backlight in one rugged package.
